Description

地下连续墙工字钢反力装置Underground diaphragm wall I-beam reaction force device

技术领域technical field

背景技术Background technique

地下连续墙是基础工程在地面上采用一种挖槽机械,开挖出一条狭长的深槽,清槽后,在槽内吊放钢筋笼,然后用导管法灌筑水下混凝土筑成一个单元槽段,如此逐段进行,在地下筑成一道连续的钢筋混凝土墙壁,作为截水、防渗、承重、挡水结构。The underground diaphragm wall is a kind of grooving machine on the ground for the foundation project. A narrow and long deep groove is excavated. After the groove is cleared, the steel cage is hung in the groove, and then the underwater concrete is poured by the pipe method to form a unit groove. In this way, a continuous reinforced concrete wall is built underground as a water interception, anti-seepage, load-bearing and water-retaining structure.

现有技术中地下连续墙在施工过程中采用工字钢进行隔断,进行分段施工,工字钢一侧用圆钢管进行支撑,但是工字钢与圆钢管始终之间存在间隙,在浇筑混凝土过程中,混凝土容易从工字钢底部溢出,渗入工字钢与圆钢管之间的间隙中,从而影响施工质量。In the prior art, the underground diaphragm wall adopts I-beams for partition during the construction process, and performs segmented construction. One side of the I-beam is supported by a round steel pipe, but there is always a gap between the I-beam and the round steel pipe, and the concrete is poured. During the process, the concrete easily overflowed from the bottom of the I-beam and penetrated into the gap between the I-beam and the round steel pipe, thus affecting the construction quality.
